  • Comment There are some capitalization issues, it seems: the word envelope in "Nuclear Envelope", "cytokinesis" in the brown label and "chromosomes" in "Metaphase II Chromosomes" all should be decapitalized. Brandmeistertalk 20:40, 1 July 2016 (UTC)[reply]
    • @ Brandmeister  Fixed. Ali Zifan 22:35, 1 July 2016 (UTC)[reply]
      • Thanks, there's one capitalized "Cytokinesis" remaining in "Telophase I & Cytokinesis" (between Anaphase I and Prophase II). Brandmeistertalk 07:59, 2 July 2016 (UTC)[reply]
      • There is also "envelopebreaks" two words, "oppisite" misspelled, "divides" singular (under Anaphase II), "(Fragments)" doesn't need capitalization if used as a descriptor rather than a noun. Bammesk (talk) 13:17, 2 July 2016 (UTC)[reply]
  • Comment: Beautifully done, but still needs some work. Apart from the above mentioned,
    • I think the "microtubule" label should be dropped. Since microtubules are the constituent structures of the spindle, labelling both seems redundant and confusing when provided without explanatory text.
    • Could the shading be adjusted to make the attached sister chromatids more distinguishable?
    • The crossing-over isn't very clear. Take a look at the bottom tetrad in prophase I. I can't quite tell which arm is attached to which. Also, in metaphase I, the crossed-over arms appear unequal.
    • The aster shouldn't be shown as sun rays; they should have the same appearance as the spindle microtubules (but shorter).
    • The "Homologous chromosomes" label in prophase I should probably point to each of the pairs, the way "Sister chromatids" does in anaphase I.
    • Typo in the anaphase I description: should be "chromosomes", not "chrmosomes".
    • The description could also be clearer. How about "separate and move" instead of just "move"?
    • Probably not necessary to show the nuclear envelope forming in telophase I only to disintegrate again right away (though the illustration in Campbell's does)?
    • Don't think we should say the spindle forms "around" the chromosomes (prophase I). Just forms is probably enough, or if necessary, "in each daughter cell".
    • "Metaphase II" probably shouldn't be repeated in the description text.
    • Minor issue, but I wonder if the central dark area in the shading of the cells is necessary. It makes the cell look like a target, and it seems to emphasise something that isn't there.
    • It would also be nice to have an image of the late interphase at the beginning, to help the viewer get a picture of the "normal" stage before division, but that's just my opinion.

  • Since microtubule and spindle are not same, I thought using both of them would be better. The file is SVG so you can it can be zoomed without using quality, so by zooming, you can distinguish minor things like attached sister chromatids. The same fact is true for crossing over part. Although the asters don't used exact same color as spindle but I used orange yellow colors for both of them. I used yellow at the center because of the centriole pair. All misspellings are corrected. Homologous chromosomes label in prophase now point to each of the pairs. The diagram clearly shows that chromatids seperate during Anaphase II so I just used "move" to make text as short as it could be. The central dark area in the shading of the cells is because of the gradient that was given to make the cell more spherically and better. Interphase stage is not necessary to be shown at the beginning because meiosis contain several important stages and adding that stage would make the diagram longer and also Interphase is already depicted in mitosis diagram .

  • You think giving a timeframe/timescale would be possible? Nergaal (talk) 23:39, 5 July 2016 (UTC)[reply]
    • If I wanted to create it, I would make it as a separate file. Ali Zifan 21:53, 8 July 2016 (UTC)[reply]
